OMAP3EVM uses ISP1504 phy which doesn't require any programming and
thus has to use NOP otg transceiver.

Cleanups being done:
	- Remove unwanted code in usb-musb.c file
	- Register NOP in OMAP3EVM board file using
	  usb_nop_xceiv_register().
	- Select NOP_USB_XCEIV for OMAP3EVM boards.
	- Don't enable TWL4030_USB in omap3_evm_defconfig

Let the otg_transceiver in MUSB be managed by an external driver;
don't assume it's integrated.  OMAP3 chips need it to be external,
and there may be ways to interact with the transceiver which add
functionality to the system.

Platform init code is responsible for setting up the transeciver,
probably using the NOP transceiver for integrated transceivers.
External ones will use whatever the board init code provided,
such as twl4030 or something more hands-off.

Partial support for DaVinci DM355, on the EVM board; peripheral
mode should work, once mainline merges DM355 support.  Missing:

  (a) renumbering the GPIO for DRVVBUS on the DM6446 EVM,
      when DAVINCI_N_GPIO increases;

  (b) disabling DM355_DEEPSLEEP.DRVVBUS_OVERRIDE so VBUS is
      driven according to the ID signal, if cpu_is_..._dm355()

The new PHY control bits are ignored on DM6446.

The Blackfin MUSB Kconfig text didn't properly parenthesise its
dependencies.  This was visible in non-Blackfin configs by the
way the user interfaces lost track of dependencies, when doing
a bunch of test builds.

The DaVinci code had an implementation of the OTG transceiver glue
too; make it use the new-standard one.

Minor musb_hdrc updates:

  - so it'll build on DaVinci, given relevant platform updates;
      * remove support for an un-shipped OTG prototype
      * rely on gpiolib framework conversion for the I2C GPIOs
      * the <asm/arch/hdrc_cnf.h> mechanism has been removed

  - catch comments up to the recent removal of the per-SOC header
    with the silicon configuration data;

  - and remove two inappropriate "inline" declarations which
    just bloat host side code.

There are still some more <asm/arch/XYZ.h> ==> <mach/XYZ.h>
changes needed in this driver, catching up to the relocation
of most of the include/asm-arm/arch-* contents.

We can change debugging level on the fly via
/sys/module/musb_hdrc/parameters/debug.

We can also get rid of the LOGLEVEL facility in Kconfig
and rely only in module parameter.

This patch adds support for MUSB and TUSB controllers
integrated into omap2430 and davinci. It also adds support
for external tusb6010 controller.
